A long coaxial cable carries a positive uniform volume charge density, ρ, on the inner cylinder (radius a), and a negative uniform surface charge density, σ, of the cylindrical shell (radius b). The surface charge has a magnitude so that the cable as a whole is electrically neutral.                                                                                                                                                                                                    find the electric potential V at the center of the coaxial cable, using s = infinity as a reference point
